Backflow Prevention Assembly Field Testing & Air-Gap Inspection: A Guide for California Water Utilities

For California public water systems, backflow prevention is not optional. Every unprotected cross-connection between a potable water supply and a potential contamination source represents a direct threat to public health. Title 17 of the California Code of Regulations (CCR) and the Cross-Connection Control Policy Handbook (CCCPH) mandate that all public water systems maintain a compliant inspection, testing, and maintenance program for every backflow prevention assembly within their service area.


Exodus Water Services provides comprehensive backflow prevention assembly field testing and air-gap inspection services to help California water agencies satisfy these regulatory requirements — with certified testers, digital record-keeping, and seamless coordination with your existing Cross-Connection Control Program.


What This Service Includes


The Backflow Prevention Assembly Field Testing & Air-Gap Inspection service covers every stage of the assembly lifecycle — from initial field verification through annual testing and emergency response. Exodus performs all work in strict accordance with the California Code of Regulations Title 17, the CCCPH, and the University of Southern California (USC) Manual of Cross-Connection Control.


What It Includes


  • Field inspection and operational testing of all backflow prevention assembly types — Reduced Pressure Zone (RPZ), Double Check Valve Assembly (DCVA), Pressure Vacuum Breaker (PVB), Spill Resistant Vacuum Breaker (SVB), and Air-Gap separation

  • Certified backflow prevention assembly testers (per CCCPH Section 5) using calibrated differential pressure gauges and approved test procedures

  • Annual testing coordination aligned with your system's test scheduling database — no missed deadlines, no lapsed assemblies

  • Air-gap inspection and verification at identified high-hazard connections per your adopted Hazard Assessment and Local Health Department ordinances

  • Digital documentation of every test result, including serialized assembly records, test gauge readings, and pass/fail determinations

  • Immediate tagging and isolation of failed assemblies, followed by repair coordination or replacement recommendations

  • 24/7 emergency response for backflow incidents involving contamination, assembly failure, or suspected cross-connection events

  • Direct submittal of test results to your CCCP administrator, DDW, or Local Primacy Agency (LPA) as required

  • Coordination with property owners, facility managers, and fire protection system contractors to schedule access for testing in commercial, industrial, and multi-family residential settings


Typical Deliverables


  1. Completed field test report for each backflow prevention assembly (digital and hard copy)

  2. Annual summary report documenting all tested assemblies, pass rates, failure modes, and corrective actions taken

  3. Updated assembly inventory reflecting any changes in assembly type, location, hazard classification, or status

  4. Certified tester affidavits and calibration records for all test equipment used during the reporting period

  5. Recommendations for assembly replacement, upgrade, or relocation where age, condition, or code changes warrant


Regulatory Framework for California Water Systems


The legal foundation for backflow prevention assembly testing in California rests on several interlocking regulations. Every public water system — from investor-owned utilities to county water districts to mutual water companies — must understand and comply with these requirements or face enforcement action from the State Water Resources Control Board (SWRCB) Division of Drinking Water (DDW).


Title 17 California Code of Regulations


Title 17, Division 1, Chapter 5, Subchapter 1, Group 4 (Sections 7583–7605) establishes the minimum standards for backflow prevention in California. Key requirements include annual testing of all backflow prevention assemblies by a certified tester, maintenance of complete test records for a minimum of five years, and immediate reporting of any assembly that fails to operate properly.


Cross-Connection Control Policy Handbook (CCCPH)


The CCCPH, published by the California Department of Water Resources and adopted by the SWRCB DDW, provides the comprehensive policy framework for implementing cross-connection control programs. It defines tester certification requirements, approved test procedures, record-keeping standards, and enforcement protocols. Exodus testers follow CCCPH Section 5 — Testing and Maintenance — to the letter.


Health and Safety Code Section 116400–116555


California Health and Safety Code provisions grant the SWRCB DDW authority to enforce cross-connection control requirements, including the power to issue compliance orders, assess penalties for violations, and direct water systems to disconnect service where an unprotected cross-connection poses an imminent public health threat. These are not theoretical powers — DDW has exercised enforcement authority against numerous California water systems in recent years.
